Put bindings and clock driver patch together from Jerome. Maybe you can read this chat history. https://lore.kernel.or/all/1jy1v6z14n.fsf@starbuckisacylon.baylibre.com/

I remember Jerome discussing this with you.You can look at this submission history. https://lore.kernel.org/all/c088e01c-0714-82be-8347-6140daf56640@linaro.org/
